Starting with the batch that just shipped out this week, we are using a new blending method. I have noticed some uneven mixing of essential oils and herbal extract powders in the past with hand mixing the ingredients by shaking and mixing the product around in Ziploc bags. We just recently acquired a professional herb grinder and are now using that to blend the TEEF Powder. I have noticed truly zero clumps since making this switch. I think you will notice a much higher quality product!
